Privacy Policy

Effective date: 24 July 2026 · Applies to the King Card Game app on all platforms and to this website.

Who is responsible

The app is developed and copyrighted by Mikhail A. Matveev (“the Developer”) and distributed on the Apple App Store by Elizaveta Fragner, Halskestr. 34 A, 12167 Berlin, Germany (“the Publisher”). For data-protection purposes relating to the app and this website you can reach us as described on the Impressum and Support pages.

Data stored on your device only

The game stores the following locally on your device, using your operating system's standard app storage. This data never leaves your device and is deleted when you delete the app:

• your settings (difficulty, sound, appearance, language and similar preferences);
• your saved single-player game so you can resume it;
• the display name you last entered for multiplayer.

Online multiplayer

If — and only if — you use the Multiplayer mode, the app connects to our game server. To run the match, the server processes:

• the display name you enter (any nickname you like — it does not need to identify you);
• your moves and room code, so the game state can be shared with the other players at your table;
• your IP address, which is technically required to maintain the connection (Art. 6 (1)(b)/(f) GDPR);
• a random session token, generated on the server and stored on your device, so you can reclaim your seat after a dropped connection.

Rooms live in the server's memory only. When a match ends or a room expires, its data — names, moves, tokens — is discarded. The server keeps no accounts, no player database and no gameplay history. Other players at your table see only your display name.

What we do not do

• No accounts, registration or profiles.
• No advertising and no ad networks.
• No analytics, tracking or fingerprinting SDKs.
• No sale or sharing of personal data with third parties.
• No access to your contacts, photos, location, microphone or camera.

Platform services

The app is distributed through Apple's App Store and Google Play. If you have enabled the sharing of diagnostics or crash reports with app developers in your device settings, Apple or Google may provide us with anonymised crash statistics. These services are governed by Apple's and Google's own privacy policies.

This website

king.rh1.tech is a static website. It sets no cookies, runs no analytics and embeds no third-party content. The web server processes IP addresses transiently in ordinary access logs for security and operation (Art. 6 (1)(f) GDPR).

Your rights

Under the GDPR you have the right of access, rectification, erasure, restriction of processing, data portability and objection, and the right to lodge a complaint with a supervisory authority. Since we hold no persistent personal data about you, in practice deleting the app removes everything stored about you; multiplayer data disappears when your room ends.

Children

The game is suitable for a general audience. We do not knowingly collect personal data from anyone, including children.

Changes to this policy

If the app ever changes what it processes, this page will be updated first, with a new effective date. Please review it from time to time.
